Apple patent filing details "touch and go" USB devices

We already caught sight of a whole batch of Apple patent applications earlierthismonth, but it looks like the company still has a few more big ideas up its sleeve, which may or may not actually come to fruition. The most interesting of those is what's described as a "Portable Device Capable of Initiating Disengagement from Host System," or a "touch and go" system as AppleInsider calls it. That, as you may be able to discern, is essentially a touch sensor tied to a USB drive or other USB device, which would be able to sense when you touch it (or even when you're about to touch it, apparently), and then disconnect the device from the computer before you're able to cause any data corruption. Better still, the system could apparently also double as a fingerprint sensor in some implementations, and completely lock down the device if an unauthorized user grabs it.
